"Tyler installed a complete septic system for our new home construction project. This included a 2000 gallon concrete tank with a distribution box and 165â of leach field. The installation was completed ahead of schedule and the site was finish graded very nicely upon completion. The system design engineer and the city building inspector both signed off with positive comments on the quality of work. We used Tyler to trench and install our water connection as well. We intend to use his services in the future also. We highly recommend him."

"I called on a Saturday morning when no other company was answering calls. They picked up and said they would be here Monday morning. They were very professional yet also let me watch and learn how to take care of my tank. I also had a clogged line and they "jetted" it and I was instantly up and running. I learned so much, I don't think I will ever need emergency service again. I will call them back in 3 or 4 years so I won't stress my system and incur more problems!"

"Hey! Santos Bros answered their phone, booked us to replace our water heater and was here 2 hours later. We have a super tight spot between our furnace and wall with a special sized 40 gallon tank. Nate got the old one out and replaced it with the right size tank, no problem. It was difficult to pull the old one out but he did a great job. Stellar service. 5 STARS. Highly recommend."

"My friend recently had some work done at his house and recommended him. I called and told him what I was looking to do and he was honest and told me how I could save money and do it myself. walked me through the process and told me who to call with the city and approximate time frames. You don't come across this type of "good people" too often these days. I highly recommend Wilber Construction. Randy will be my first call in the future for any type of construction work. Thanks Randy!"

Septic Tanks FAQs, answered by experts

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

While dry wells can be effective for managing rainwater, they have several disadvantages. They can become clogged with sediment, especially after large storms, which reduces their effectiveness and can be difficult to clean. Dry wells are also not suitable for all soil types; they will not function properly in soil with low permeability. Additionally, if a dry well is not large enough to handle the amount of rainfall in your area, it can overflow. For gravity-flow models, the water may disperse very slowly, depending on the well's depth and the soil's permeability.

When a septic tank is full, it needs to be professionally pumped. The average cost of a one-time septic tank pump is about $400, or $0.30 per gallon. If your septic tank is full, you may notice that you have issues flushing your toilet, pipes are draining very slowly, or you have a sewage smell lingering in your home or yard.

You may want to increase the size of your leach field, for instance, if you add on to your home or install more bathrooms in your house. You can make your leach field larger by installing more pipes or expanding the area of the field itself. Improving the soil quality in the drain field can also make it more effective without increasing the area.

Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are perforated, or drilled with small holes, so the wastewater can drain out of the pipes and into the surrounding material, which eventually leads to the aquifer.
